SCEJ has a sort of special demo for your web browser that may give you a feel for what kind of thinking and game play you can expect with Echochrome II. In this game you'll use the PlayStation Move to move and adjust shadow to solve puzzles. Your mind will have to work in 3D to figure out what you'll need to do next. Sometimes you'll even need to create a shadow puppet by manipulating a light source.
This Shadow Factory demo lets you make your own shadow puppets. You're given tools to plot blocks and shapes in a 3D space. When you're done, hit the gear button and watch your creation animate. If you did something nifty, you can even export it as an animated GIF. Pretty neat.
I made this abstract Dtoid head above. When I tried to animate it, the head walked off and left the eyes. The mouth wavered loosely. Fail.
